When implementing stateful parsing (e.g., direction/context tracking with stacks), treat correctness as a property of the whole scan loop—not just the “main” match. Apply these rules: - Don’t use `continue` (or similar early-skip control flow) in ways that prevent subsequent tokens/characters on the same iteration/input segment from being processed. If multiple tags/tokens can exist close together, ensure nothing that could affect output/state is skipped. - If a line can contain multiple relevant tags, extract *all* matches on that line and process them in textual order, updating your context stack deterministically (push on opening, pop on closing). - Document the intent (especially why multiple tags on the same line must be handled) and the meaning of match groups/tuples so future edits don’t regress correctness. Example pattern (process all `

` tags on a line, in order): ```py # Find all opening and closing

tags on the line div_tags = re.findall( r"(]*dir=['\"](rtl|ltr)['\"][^>]*>|

)", line, re.IGNORECASE, ) for tag, direction in div_tags: if tag.startswith('' and len(block_context_stack) > 1: block_context_stack.pop() ``` Add/keep tests that cover: (1) multiple tags on the same line and (2) cases where skipping tokens would drop nearby output characters (e.g., punctuation around inline spans).
